NAIL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 465,762, dated December22, 1891.

Application filed July 16, 1891. Serial No. 399,740. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. HOUGHTON, a citizen of the United Statesof America, residing at Northumberland, in the county of Northumberlandand State of Pennsylvania,

hereinbelow made.

I have fully and clearly illustrated my invention in the accompanyingdrawings,wl1ere- 1n- Figure 1 is a plan View of a nail-machine with thecutting-jaw and lever removed and other'parts partly in section andhaving my present improvements connected thereto.

Fig. 14 is a detailside view of the bed-gripping die with the ejector removed, and Fig. 15is an end view of the stationary bed-piece with the dies and ejectorsarranged therein.

In Fig. l of the drawings I have illustrated the well-known high-postnail-machine, and. reference being made thereto, A designates the bed orframe of the machine; B, the driving-shaft; O, the heading-lever, and Dthe gripping-lever. These elements are of the usual constructions,excepting that the driving-shaft has an extra cam a, formed thereon, tooperate the vertically-moving lifting-post of the push-bar of thenipper-bar, as hereinafter more fully specified.

My present invention includes and embraces improvements of this push-barin combination with a longitudinally-reciprocating nipper-bar forlaterally moving the pointcuttingmoving die, as well as having the usualreciprocations for partially moving the nipper.

In the front of the bed-frame'of the machine is formed the usual chamberor seat 1) for taking the bedpiece, dies, and bed-knife of the machine,and on the top face of the gripping-lever is formed the usual seat 0 forthe moving die-case and its contained dies.

The means or mechanism for imparting the vertical and horizontalreciprocations to the nipper-bar and correspondingly affecting thenipper are the same as those described and shown in my pendingapplication for Letters Patent, Serial No. 378,958, and hence no claimis made herein for these means exextended and rests on the bed of themachine alongside of the knife-bed, as shownat 6. The nipper-bar 7 isloosely supported 011a pin 8 at its end in a bearing 9, so as to giveIIO the requisite play, and has its inner end connected to the sliding nipper. In the push-bar is notch 10, in which the nipper-bar engages andis held. On the post of the machine adjacent to the nipper-spring arekeepers 11, in which a post 13 is arranged to have vertF cal movement.This post 13 is formed with an arm 14, which bears on the cam a on thedriving-shaft, and operates to lift the post. The post is also providedwith an inwardlyprojecting arm 15, which engages the projecting end ofthe lug of the push-bar under the eyebolt, as shown, so that when thevertical post is raised the push-bar is tilted, and the nipper-bar isthereby raised and the nailblank carried under thelip of the back piece.

In my present invention I give the nipperbar an additional and importantfunctionthat is, I make it longitudinally movable to operate apoint-cutting die on the gripping-lever, and to effect this change theconstruction differs from that described as follows: The rear end of thenipper-bar is formed with an elongated slot 16, in which the pin 8 isprojected as a bearing, and on which the nipperbar has longitudinalmovement. Near the outer or free end of the nipper-bar is a vertical lug17, made wide enough to set in a recess in the slidding nipper andextend across a recess 18 in the die case or piece and bear with itsedge against the inner face of the moving point-cutting die and serve topull that ele ment outward and give it a shearing movement in theoperation of cutting the point on the nail. The end 19 of the nipper-barextends a short distance beyond the side of the die, as seen in Figs. 1%and 2 of the drawings, and is engaged by the header just as it comes upto form the head on the nail when held between the dies.

E designates the moving bed-die holder or die-case adapted to be securedon a seat a in the gripping-lever. This die-case has formed in one ofits sides a seat 21, in which is arranged the gripping-die. In the undercentral portion of the die-case is formed a seat 23 for the slidingnipper and in the other side is a seat 24 for the point-cutting die 25.The seat 24 is made wider than the point-cutting die, so that it mayhave alimited lateral movement in the seat. The face end of thediecaseis formed with alip 26, form ed by the lower portion beingextended beyond the upper, substantially as shown. The standing metal orwall 27 of the die-case between the nipper-seat and the point-cuttingdie chamber or seat is recessed or cut away, as at 18, for a distance ofits height to permit the lug on the nipper-bar to slide back and forthin its horizontal reciprocations when moved by the header. The nipper 29consists of a bar of steel arranged in the die-case and having an endface to conform with the contour of the end face of the die-case, andalso having its under face formed with a shoulder 30 and a recess 31atits rear portion, as shown. Across the bottom of the die-case issecured a stoppiece 32, which permits the nipper to have a longitudinalmovement limited by the recess 31, and to the back of the nipper 1s aspring 33, which bears down on the nipper when in its" seat and servesto move the nipper downward when carried outward beyond the shoulder.This construction of the nipper is the same as that seen in my pendingapplication, Serial No. 378,958, heretofore mentioned. The difference ofconstruction being that in the said cited application the nipper isformed with a lug on its lower face engaged by the nipper-bar, while inthe present invention, necessarily so, in yiew of the longitudinalmovement of the n1pper-bar, a transverse groove or recess 33 is formed1n the nipper, in which the lug on the nipperbar engages. Thepoint-cutting d e 25 is of the same construction as that shown in mysaid application, Serial No. 378,958, and consists of a steel bar havinga point-cutting groove in its face end and being made narrower than theseat in the die-case to give it room for lateral movement therein. Therear end of this die has a dovetail connection or o nt 1n a short block34, to have alimited play n the joint, and the forward position of thedie is adjusted and fixed by means of an adj Listingscrew 35,substantially as shown.

F designates the stationary bed-piece or die-case having a lip 36,formed across ts end face, arranged at a higher plane than the lip ofthe moving die-case. This bed-piece also has a side recess or chamber37, in which is lodged the point-cutting die 38. Thisdieis narrower thanthe recess, in order that it may have a limited lateral movement in itsseat in connection with the opposing moving d1e. In the under centralpart of the bed-piece 18 a groove 39, in which is lodged the centralejector 40, forced outward byaspring 41, and stayed in its outwardmovement by a crosspiece 42 bridging the groove and engaging ill arecess 43 in the ejector.

The foregoing described constructions are substantially identical withthose shown and described in my said pending application, Serial No.378,958, and no special claim is made to them herein.

G designates the bed-gripping die. This die is lodged in the recess 44and is formed with a score 46 across its face, as shown, and in the sideof the die is a groove extending well back, as shown, and having anopening 47 through the wall of the groove to take the lug on the end ofthe auxiliary ejector arranged to have a limited movement in the grooveor seat.

50 designates the auxiliary ejector consisting of a bar fitted in thegroove of the die and formed with a lug 51, arranged in the opening 47in the die. A spring 52 in the rear end of the groove of the die forcesthe auxiliary ejector to stand normally out with its face flush with theend of the die. This auxiliary ejector serves the purpose of freeing thenail from the die after the head has been struck thereon,the blankhavinga tendency to stick in the score of the die because of the forceof the grip when in the dies. A spring 53 returns the die 38 to itsnormal or straight position afterbeing moved out in the operation ofcutting the point, and a spring 54 serves the same purpose in the movingpoint-cutting die.

The operation of the improved mechanism is as follows: The nail, beingcut from the plate and carried down by the cutting-knife, (not shown,)is engaged by the nipper, which in its forward and upward movementcarries the cut blank against and up and under the lip of the bed-piece,where it is engaged by the moving dies and held until the header comesup to form the head, which, just before reaching the head and While thecutting-dies are making the point, the header engages the end of thenipper-bar and pushes that enclwise, sliding it on the slot at itsbearing and moving the point-cutting die, and thus gives the dies alateral shearing or pinching movement and cutting and cleaning thepoint. The nipper is reciprocated vertically longitudinally by means ofthe push-bar. After the nipper-bar has been moved endwise by the headerit is carried back by the die when the spring returns that element toits normal position.

Having thus described my invention, explained its principle, and statedits operation,

' so as to distinguish it from other inventions in the art, as requiredby the statute, I now proceed to particularly point out and distinctlyclaim the parts, improvements, and combinations I claim as my invention,as follows:
